Project Opportunity Finding or Account Mining is an approach used by companies, especially software companies, to find new opportunities from existing clients during economic downturns. It involves gathering detailed information about client accounts, analyzing client needs and capabilities, and creating documents that propose new projects or services based on gaps identified. Studies show companies using this approach gained 10-20% more projects compared to those relying solely on goodwill. The approach builds stronger client relationships and allows companies to provide more value-added consulting.
